There is a protest against this today in Regina.
I don't actually have a problem with refusing to let someone in a store if they have repeatedly been a problem. I deal with that myself, though I have never refused anyone service.
There is a big difference between that and writing it into the law, and having the cops enforce something that isn't based on court decisions, but on the whims of some shopkeeper. This has been happening for years on an informal basis in malls. Having it become police policy, like other similar vigilante and citizens arrest laws, is a step in the wrong direction.
How long before this becomes a de facto "No Native or Poor People" law?

Cops say it is working though. Must be a good thing then:
